INTRODUCTION

The 694 Master (MS-6309 ver 3.0) ATX mainboard is a high-performance

computer mainboard based on VIA VT82C694X chipset. The 694 Master

(MS-6309 ver 3.0) is designed for the Intel CeleronTM or Coppermine (FC-

PGA) processor for inexpensive business/personal desktop markets.

The Apollo Pro133A (VT82C694X) is a Socket-370 system logic north bridgewith the addition of 133 MHz capability for both the CPU and SDRAM

interfaces. Apollo Pro133A may be used to implement both desktop and

notebook personal computer systems from 66MHz to 133MHz based on

Socket-370. The primary features of the Apollo Pro133A-North Bridge are:

Slot-1 or Socket-370 CPU (Front Side Bus) Interface (66 / 100 / 133MHz),

DRAM Memory Interface (66 / 100 / 133MHz), AGP Bus Interface (66MHz),

PCI Bus Interface (33MHz), Mobile Power Management.

The VT82C686B PSIPC (PCI Super-I/O Integrated Peripheral Controller) is a

high integration, high performance, power-efficient, and high compatibility

device that supports Intel and non-Intel based processor to PCI bus bridge

functionality to make a complete Microsoft PC99-compliant PCI/ISA system.
